Swiss-PDBViewer = DeepView

DeepView, formerly known as Swiss-PDBViewer, is a powerful free molecular modeling program by Nicolas Guex, Alexandre Diemand, Manuel C. Peitsch, & Torsten Schwede of the Swiss Institute of Bioinformatics. It is one of the most powerful free modeling programs available, and has been for many years. It can be used for structural alignments, homology modeling, mutating molecular models, energy minimization, and many other modeling tasks. For tutorials, step-by-step instructions, and other help, please see the DeepView section of the World Index of Molecular Visualization Resources, MolVisIndex.Org. The program itself can be downloaded from the official DeepView website.
